EPF8820ATC144-2N 概述

The Altera (Intel) EPF8820ATC144-2N is a FLEX 8000 family Field-Programmable Gate Array (FPGA) delivering 8,000 usable gates, 672 logic elements, and 112 user I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package. Built on a 0.42 µm CMOS SRAM process and operating from a 5 V supply, it supports in-circuit reconfigurability through external configuration EPROMs or Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration devices, enabling system-level flexibility for prototyping and field updates.

A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that an engineer can program to implement arbitrary digital logic, glue logic, bus interfaces, state machines, and signal-processing datapaths. Within the broader taxonomy, FPGAs sit alongside CPLDs in the programmable logic hierarchy and are categorized under Integrated Circuits > FPGA & CPLD. FLEX 8000 was Altera's register-rich, high-density family positioned between simpler Classic EPLDs and the larger FLEX 10K family that introduced embedded array blocks.

Key features of the EPF8820ATC144-2N include 84 logic array blocks (LABs), 112 maximum user I/O pins, and a maximum toggle frequency of 125 MHz. The device supports multi-voltage I/O operation (TTL and CMOS interfaces) and offers fast in-system configuration via the FLEX configuration scheme. The high-pin-count 144-TQFP package integrates multiple 32-bit buses into a single device, allowing dense glue-logic and peripheral-bridge designs.

The EPF8820ATC144-2N uses Altera's classic 4-input look-up table (LUT) architecture with a continuous routing network, providing predictable timing and good register-to-logic ratios suited for state machines, datapath registers, and address decoding. The 5 V core is robust for legacy industrial interfaces and TTL buses.

Typical applications include TTL and bus integration (PCI bridges, ISA glue logic), high-speed controllers, coprocessor functions, DSP preprocessing, wide-data-path manipulation, and address/data translation between mismatched processor peripherals. The 112 I/Os comfortably handle 32-bit datapaths plus control.

When designing with this part, ensure correct configuration mode selection (FLEX configuration scheme), proper decoupling of the 5 V rail, and observance of TQFP-144 PCB land pattern guidelines for reliable hand or reflow soldering.

典型应用

EPF8820ATC144-2N 适用于 6 应用s: TTL and Bus Interface Integration, High-Speed State Machine Controllers, Coprocessor and DSP Pre-Processing, Wide Datapath Manipulation and Bus Width Conversion, Industrial Control and Instrumentation, Legacy System Field-Upgradeable Logic.

🖥️

TTL and Bus Interface Integration

The EPF8820ATC144-2N's 112 user I/Os and 5 V TQFP-144 footprint make it ideal for TTL bus and peripheral glue logic. The device can absorb 32-bit address/data buses plus control signals, replacing multiple 74-series TTL packages with a single programmable device. 5 V CMOS I/O is directly compatible with TTL thresholds, and 125 MHz internal frequency easily handles fast ISA-style or memory-mapped bus cycles. Use it to consolidate address decoding, chip-select generation, and wait-state insertion.

🏭

High-Speed State Machine Controllers

With 672 logic elements, 84 LABs, and 125 MHz internal frequency, the EPF8820ATC144-2N implements complex multi-state controllers, sequencers, and protocol engines. Its register-rich FLEX 8000 architecture favors state-machine implementations where each LE pairs a 4-input LUT with a flip-flop. Typical targets include motor-control sequencers, communication-protocol state machines (UART, SPI, I2C bridges), and industrial automation controllers. Timing closure at 50–80 MHz state-machine rates is comfortable on this device.

🎧

Coprocessor and DSP Pre-Processing

The EPF8820ATC144-2N's 8,000-gate capacity and register-rich fabric make it well-suited to DSP pre-processing and coprocessor functions in front of a host processor. Common implementations include FFT pre-stages, FIR/IIR filter pipelines, CRC engines, and data-format converters. The 112 I/Os support parallel high-speed datapaths to external SRAM or DSP chips. At 125 MHz the device comfortably runs fixed-point multiply-accumulate arrays at audio and baseband rates.

🔧

Wide Datapath Manipulation and Bus Width Conversion

The EPF8820ATC144-2N integrates multiple 32-bit buses into a single device, supporting wide-datapath manipulation between mismatched processor peripherals. Use it as a bridge between 8/16/32-bit microcontrollers and external memory, as a byte-swapping engine for endian conversion, or as a streaming FIFO controller. The high-pin-count TQFP-144 package exposes enough I/O for full 32-bit buses plus parity, byte-enables, and hand-shake signals without external muxes.

🏭

Industrial Control and Instrumentation

The 5 V tolerant I/O and 0–70 °C commercial temperature range of the EPF8820ATC144-2N suit legacy industrial control and instrumentation systems. Implement custom timing controllers, pulse-train generators, encoder interfaces, and process-control state machines on this device. The 5 V supply simplifies retrofit designs where 3.3 V FPGAs would need level shifters. Many long-lifecycle industrial and military customers continue to specify FLEX 8000 due to its mature, well-documented tool flow.

🧩

Legacy System Field-Upgradeable Logic

The EPF8820ATC144-2N supports in-system reconfigurability via Altera EPC1/EPC1064/EPC1213/EPC1441 configuration devices, enabling field-upgradable logic in deployed systems. This is valuable for legacy products requiring post-deployment bug fixes, feature additions, or protocol updates without board rework. Engineers can store multiple bitstreams and swap configurations to support different operating modes, diagnostic revisions, or hardware revisions in the field.

What family does the EPF8820ATC144-2N belong to?
The EPF8820ATC144-2N belongs to Altera's FLEX 8000 family of CMOS SRAM-based FPGAs. According to the datasheet description on altera d ocumentation, FLEX 8000 provides up to 16,000 usable gates and is configured at system power-up via parallel EPROM, Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration devices, or a system controller, giving in-system reconfigurability for prototyping and field updates.
How many gates and logic elements does the EPF8820ATC144-2N have?
The EPF8820ATC144-2N contains 8,000 usable gates, 672 logic elements (cells), and 84 LABs/CLBs. These figures come from distributor parametric data (DigiKey, Arrow) and the GlobalSpec datasheet entry. The logic elements are organized as 4-input LUTs with register-rich architecture, suitable for state machines, datapath registers, and wide-bus glue logic.
What is the maximum operating frequency of the EPF8820ATC144-2N?
The EPF8820ATC144-2N supports a maximum internal operating frequency of 125 MHz. This rating applies to the global clock network and register-rich logic paths. Practical design frequency depends on routing congestion, fan-out, and I/O standard, so timing closure should be verified in Quartus or MAX+PLUS II timing reports for the specific design.
What package does the EPF8820ATC144-2N use?
The EPF8820ATC144-2N uses a 144-pin Thin Quad Flat Pack (TQFP) package with gull-wing leads and surface-mount termination. The high pin count supports 112 user I/Os, allowing multiple 32-bit buses to be integrated into a single device, which is the central value proposition of the FLEX 8000 family in TQFP-144.
Is the EPF8820ATC144-2N still in production?
No. The EPF8820ATC144-2N is listed as obsolete by distributors such as DigiKey. The FLEX 8000 family was discontinued by Altera (now Intel) in favor of newer Cyclone and MAX families, although authorized stocking distributors continue to ship remaining factory and channel inventory for legacy and long-lifecycle customers.
Where to buy EPF8820ATC144-2N online?
The EPF8820ATC144-2N is available from authorized Altera/Intel distributors including DigiKey (stock listing visible), Arrow Electronics, and several brokers. As of 2026-09-12, Octopart reports approximately 760 pieces across the channel. Because the part is obsolete, buyers should confirm RoHS status and date code before placing production orders.
What is the price of the EPF8820ATC144-2N?
Pricing as of 2026-09-12 ranges from approximately USD 38.50 at qty 1 to USD 18.95 at qty 1000, based on distributor listings. Obsolete parts typically carry price premiums due to limited remaining inventory. For high-volume or long-term support, consider migrating to a Cyclone IV or Cyclone 10 LP equivalent that fits a similar TQFP-compatible footprint.
What is the lead time for EPF8820ATC144-2N?
Lead time for EPF8820ATC144-2N varies by distributor and is typically 2–6 weeks for stocked inventory, or extended for special orders. Because the part is obsolete, lead time can stretch when channel stock is depleted. Engineers designing new products should plan for migration to a current-generation FPGA, since Altera does not accept new orders for FLEX 8000.
EPF8820ATC144-2N vs EPF8820ATC144-4N — which is better?
EPF8820ATC144-4N is a faster speed-grade variant of the same FLEX 8000 die with 144-TQFP package, while EPF8820ATC144-2N is a slower speed-grade. Choose -4N for higher timing margin (close to 125 MHz internal); choose -2N for cost-sensitive applications where the design runs well below the speed ceiling. Both are pin-compatible drop-ins in the same TQFP-144 footprint.
What is the best drop-in replacement for EPF8820ATC144-2N?
The best drop-in replacement for EPF8820ATC144-2N is EPF8820ATC144-3 (or -4N for higher speed), all sharing the same FLEX 8000 die and 144-TQFP package. For pin-compatible TQFP-144 FPGAs from the same family but different speed grade, the -3N, -4N, -10N, and -12 speed-grade suffixes drop into the same socket without PCB rework.

Configuration is via Altera EPC1, EPC1064, EPC1213, or EPC1441 devices.
Can the EPF10K10TC144-4 replace the EPF8820ATC144-2N?
The EPF10K10TC144-4 is pin-compatible in TQFP-144 footprint but is a FLEX 10K device (Altera's larger family with embedded array blocks) and provides 576 logic elements versus 672 in the EPF8820ATC144-2N. It is not a strict drop-in — FLEX 10K uses a different configuration bitstream and tool flow (MAX+PLUS II). Migration requires recompilation and timing re-verification.

选型指南

Choose the EPF8820ATC144-2N when you need a 5 V-tolerant FLEX 8000 FPGA in TQFP-144 with moderate speed requirements (timing margin adequate for designs running well below 125 MHz) and you specifically want the -2N timing bin to minimize cost on legacy designs. Choose EPF8820ATC144-4N for higher timing margin on faster designs, EPF8820ATC144-3 as the typical balanced choice, or EPF8820ATC144-10/12/15 for cost-down designs with relaxed timing. For new designs, consider migrating to the Altera Cyclone IV EP4CE6 in TQFP-144, which is pin-compatible for many FLEX 8000 designs and provides active lifecycle support with Quartus II tools. For all alternatives, the same TQFP-144 land pattern is used, enabling PCB layout reuse across speed grades.

关键差异点

  • Same die as other EPF8820ATC144 speed grades (对比 EPF8820ATC144-3)
  • Smaller 144-TQFP vs 208-RQFP package option (对比 EPF8820ATC144 in 208-RQFP)
  • Drops into TQFP-144 sockets of pin-compatible family members (对比 EPF10K10TC144-4 (FLEX 10K))

设计说明

The EPF8820ATC144-2N operates from a single 5 V VCCINT supply with separate VCCIO rails for I/O banks. Decouple each VCCINT and VCCIO pin with a 0.1 µF ceramic capacitor placed as close as physically possible to the package pin, plus a bulk 10–47 µF tantalum or aluminum polymer cap near the package. In-rush current during configuration can momentarily spike; size the regulator for at least 1.5× the steady-state ICC. Configure unused I/O pins as outputs driving low to minimize power and ground-bounce.

TQFP-144 land pattern follows JEDEC MS-026 with 0.5 mm pitch and 1.6 mm×1.6 mm lead footprint. Use a 4-layer PCB with continuous ground plane directly beneath the device to provide thermal dissipation and low-impedance return paths. Keep configuration traces (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) short and away from switching I/O to avoid coupling during programming. Use a pull-up on nCONFIG and CONF_DONE per the FLEX 8000 configuration scheme datasheet section.

Do not assume all FLEX 8000 speed grades share the same configuration bitstream — Quartus or MAX+PLUS II generates a different bitstream for each speed grade and package combination, even though the die and pinout are identical. Programming a -4N bitstream into a -10 device may function but with reduced timing margin. Conversely, programming a -2N bitstream into a -4N device will fail timing analysis and could cause metastability on fast paths. Always recompile the design for the target speed grade.

The EPF8820ATC144-2N is from the original FLEX 8000 family (pre-2000s 5 V era) so RoHS compliance is not verified in available distributor listings. Compliance status marked 'unknown' pending direct inquiry with the original Altera/Intel legacy FPGA archive. Not applicable for AEC-Q100 — FPGAs are typically not automotive qualified unless explicitly noted in the datasheet.
